Title (EN) FAULT DETECTION METHOD FOR HIGH-VOLTAGE DIRECT CURRENT CIRCUIT AND HIGH-VOLTAGE DIRECT CURRENT CIRCUIT
(FR) PROCÉDÉ DE DÉTECTION DE DÉFAUT DE CIRCUIT À COURANT CONTINU HAUTE TENSION ET CIRCUIT DE COURANT CONTINU HAUTE TENSION
(ZH) 高压直流电路的故障检测方法及高压直流电路
Abstract:
(EN) A fault detection method for a high-voltage direct current circuit and the high-voltage direct current circuit. The method comprises: acquiring, when a part to be detected is in a state of being disconnected from remaining parts of a high-voltage direct current circuit, a first resistance value of an output end of the part to be detected and a second resistance value of an output end of the high-voltage direct current circuit; and determining, on the basis of the first resistance value and of the second resistance value, a fault state of the part to be detected and of the remaining parts of the high-voltage direct current circuit. The method allows the precise determination of a specific part that is faulty.
(FR) L'invention concerne un procédé de détection de défaut d'un circuit à courant continu haute tension et le circuit à courant continu haute tension. Le procédé comprend consiste : à acquérir, lorsqu'une partie à détecter est dans un état déconnecté des parties restantes d'un circuit à courant continu haute tension, une première valeur de résistance d'une extrémité de sortie de la partie à détecter et une seconde valeur de résistance d'une extrémité de sortie du circuit à courant continu haute tension ; et à déterminer, en fonction de la première valeur de résistance et de la seconde valeur de résistance, un état de défaut de la pièce à détecter et des parties restantes du circuit à courant continu haute tension. Le procédé permet la détermination précise d'une partie spécifique défectueuse.
(ZH) 一种高压直流电路的故障检测方法及高压直流电路。该方法包括:获取待检测部件与高压直流电路的剩余部件之间处于断开状态时,待检测部件的输出端的第一电阻值和高压直流电路的输出端的第二电阻值;根据第一电阻值和第二电阻值,确定待检测部件和高压直流电路的剩余部件的故障状态。该方法可以精确地确定出已出现故障的具体部件。
